Space alert: Hazardous asteroid nears Earth

Posted by Ram Kumar Shrestha on January 10, 2013

alert-hazardous-nears-asteroid.nAll eyes are set at the skies as a big hazardous asteroid is nearing Earth. According to scientists there is an actual possibility that the 300-meter-wide Apophis will eventually strike our planet, but the catastrophe is not imminent.

On Wednesday the dangerous space traveler is passing Earth at 14 million km – the distance which raises no concerns. Apophis near approach, which may have been observed around 00:00 GMT, was traced by Slooh Space Camera.

The asteroid is planning a series of come backs of which the one in 2036 is said to be most threatening.

Named after the Ancient Egyptian evil demon, Apophis was discovered in 2004. The initial estimations indicated the probability that in 2029 the asteroid would strike Earth. However, additional calculations lessened this possibility and postponed it till 2036.

According to NASA scientists in 2029 Apophis may pass through a gravitational keyhole which would change his orbit causing imminent collision with Earth in 2036.

Russian scientists are planning to plant the asteroid with a radio beacon to trace its orbit and the risks Apophis pose to our planet. But the mission will only take place after 2020. Read the rest of this entry »

4d

So you’ve just gotten used to 3D cinema. What’s next?

4D, of course.

Up to 200 cinemas in the United States are set to be outfitted with ‘smell-o-vision’, as well as moving seats and other special effects, in an attempt to keep ahead of the developments in home cinemas.

The South Korean company CJ Group hopes that the equipment will boost the cinema industry.

Along with the smells and movement, the cinemas could include ‘back ticklers’ — designed to rub your back in a ‘realistic’ manner, as actors fall into objects. Read the rest of this entry »

‘Internet Doomsday’ Fizzles As Most Users Remove Crippling Virus In Time

Posted by Ram Kumar Shrestha on July 10, 2012

Huffington Post UK  |  By 

Dns Changer  

It may have been called ‘Internet Doomsday’ – but the decision to switch off a temporary fix to a virus which could have thrown thousands offline appears to have had little impact.

The DNS Changer virus spread almost a year ago, and was written to change a user’s internet settings to make them visit fraudulent websites.

But when the fraud was discovered so many computers were reliant on the hackers’ servers the FBI had to keep them switched on, or thousands would lose Internet access.

Up to four million machines were originally infected in the US, but by Sunday that was thought to be around 300,000.

Italy (26k), Germany (18k) and India (21k) all had thousands of infected machines, and up to 20,000 UK computers were said to be affected. Read the rest of this entry »

Stephen Hawking: ‘I Held A Party For Time-Travellers… But None Came’

Posted by Ram Kumar Shrestha on July 3, 2012

Hawking

Stephen Hawking recently gave a party – for time travellers.

But while he told plenty of people about the date, sent out invitations and waited patiently for them to arrive, no body came.

Of course that might have been because he waited until the party was over to send out the invites.

Professor Hawking explained his failed experiment in a recent interview with various journalists, written up by Ars Technica.

“I have experimental evidence that time travel is not possible,” he said.

“I gave a party for time-travellers, but I didn’t send out the invitations until after the party. I sat there a long time, but no one came.”

Hawking has previously spoken about the party, which was ‘held’ on 28th June 2009, and produced a video about the experiment – but due to the laws of causality, no one has retrospectively showed up.

Hawking also said that Einstein’s theories offer the possibility of travelling backwards in time – but “it is likely that warping would trigger a bolt of radiation that would destroy the spaceship and maybe the space-time itself”.

In the interview Hawking was also asked about alien life – and reassuringly said that it isn’t likely aliens are coming to visit.

“I’m discounting claims that UFOs contain aliens. Why would they appear only to cranks and weirdos?” he asked. Read the rest of this entry »

World’s Biggest Photo: 272 Gigapixel Image Made With Canon 7D Camera

Posted by Ram Kumar Shrestha on April 30, 2012

 

272 Gigapixel Image Biggest In World
You’re looking at the world’s largest photo.

The whopping shot of Shanghai is 272 gigapixels, and was made with a £1000 Canon 7D Camera.

It’s size outshines a 70 gigapixel (70 billion pixels) whopper of Budapest, an 80 gigapixel image of London , a remarkable 26 gigapixel image of Dresden and an 8 gigapixel image of the Milky Way.

To compare the shot you your average household digital camera snaps shots, they usually come up between two and 20 megapixels.

The amazingly detailed image won a competition to create the world’s largest digital photo.

It’s not just one shot though, the massive image is 12,000 photos stitched together.

So how big is a 272 gigapixel image exactly? 1 gigapixel is 1000 megapixels, which is 1 billion pixels. So we’re looking at 272 billion pixels, which is large enough to cover 7000 billboards. Read the rest of this entry »

Mars: ‘Life On The Red Planet Is 99% Certain’ As 1976 Samples Taken By Nasa’s Twin Viking Landers Are Revisted

Posted by Ram Kumar Shrestha on April 13, 2012

 

New analysis of soil samples taken on a Mars mission in 1976 have revealed evidence of life, a report claims.

The samples, collected by Nasa’s twin Viking Mars landers, were initially thought to show proof of geological activity, but not biological evidence.

But new analysis by researchers at the University of Siena and California’s Keck Institute believe the original experiments may have been flawed and that there was proof of microbial life.

“On the basis of what we’ve done so far, I’d say I’m 99 per cent sure there’s life there,” said Joseph D Miller, associated professor of cell and neurobiology at the University of Southern California’s Keck School. Read the rest of this entry »

The Whole Universe In One Photo

Posted by Ram Kumar Shrestha on April 4, 2012


Comment: Thanks NASA for giving opportunity to have a look to the whole universe sitting on chair:

Nasa has unveiled an astounding new image of our galactic neighbourhood – a new star atlas for the entire universe.

The atlas includes a catalogue of the entire infrared sky, over half a billion stars, galaxies and more captured by the Wide-field Infrared Survey Explorer (WISE) mission.

Edward Wright, WISE principal investigator at UCLA, said: “Today, WISE delivers the fruit of 14 years of effort to the astronomical community.” Wright began working on the WISE mission in 1998.

Made up of more than 2.7 million images taken at four infrared wavelengths of light, the new image captures everything from nearby asteroids to distant galaxies. Read the rest of this entry »

Nasa Video Shows Moon Was Once A Huge Fireball – PHOTOS, VIDEO

Posted by Ram Kumar Shrestha on March 19, 2012

  

An amazing new animation from Nasa shows how the grey, puckered rock that is our moon, was once a flaming inferno under asteroid attack.

The video shows that the moon was not always the cool, scarred rock we’re used to seeing today; 4.5 billion years ago, it was a flaming hot mass of lava.

Then, 0.2 billion years later, the Aitken basin at the moon’s south pole was formed by asteroid strike before the the moon came under mass assault by further asteroids between 4.1 and 3.8 billion years ago, forming several basins across the celestial body. Read the rest of this entry »

Yahoo Sues Facebook

Posted by Ram Kumar Shrestha on March 13, 2012


Business war:

Yahoo is suing Facebook over patents, weeks before the social-networking heavyweight is due to cash in with its initial public offering of stock.

Yahoo said in a US court filing that Facebook had infringed 10 of its patents covering advertising, privacy controls and social networking.

Yahoo had threatened to sue Facebook last month, insisting that the social network license its patents. Facebook vowed to defend itself vigorously against what it called “puzzling actions” by Yahoo.

“We’re disappointed that Yahoo, a long-time business partner of Facebook and a company that has substantially benefited from its association with Facebook, has decided to resort to litigation,” Facebook said. Read the rest of this entry »

Stephen Hawking To Make Cameo In ‘The Big Bang Theory’

Posted by Ram Kumar Shrestha on March 12, 2012

Physicist Stephen Hawking is to make a cameo appearance in American sitcom The Big Bang Theory.

The eminent scientist, who recently turned 70, will turn up in the show after filing his spot on a recent trip to California.

Hawking will guest star on the CBS-produced show on 5 April.

For those familiar to the programme, we’re informed Hawking will meet Sheldon, the most neurotic and nerdy genius among the four nerdy geniuses at the show’s core.

Sheldon was pranked in previous episode with a fake voicemail supposedly from the brilliant scientist. Read the rest of this entry »

Facebook Pages Now Get Timeline

Posted by Ram Kumar Shrestha on February 29, 2012

Facebook Timeline for pages has just been released, bringing the new Timeline look to the brand and organisation pages you “like” on Facebook.

All pages will switch to the new design by March 30, whether or not brands optimise their profiles, and add a big header image.

Any Facebook change naturally brings out some love and hate. Some brands will love it, especially those who update their pages often. For others, it will show up how infrequently they update their page.

Facebook users took to Twitter to vent their spleen over the change, with feelings evenly split between love and hate.

Ian Schafer from Deep Focus told Mashable: “It’s an opportunity for brands to tell more engaging stories on Facebook than they can now,” Schafer said. “It puts them more in control of their content.” Read the rest of this entry »

CERN’s Loose Cable To Blame For Proving Einstein Wrong

Posted by Ram Kumar Shrestha on February 26, 2012

Note to Einstein naysayers – check your equipment before trying to prove the chief geek wrong.

A loose wire may be to blame for CERN’s claim late last year that Einstein’s theory of special relativity, proposed in 1905, was actually incorrect.

The theory states that nothing in the universe can travel faster than the speed of light in a vacuum.

It took just 2.3 milliseconds for light to travel between the Geneva and Gran Sasso laboratories.

CERN showed that the accepted speed of light could be broken by 60 nanoseconds, or more precisely that neutrinos arrived 60 nanoseconds too early than if they were travelling at the speed of light, breaking the speed of light itself by 0.00248%. Two experiments reached the same conclusion.

The Telegraph reports that a loose wire at CERN might mean Einstein is not wrong. Read the rest of this entry »

‘Marsquake’, How Earthquakes On Mars Could Sustain Alien Life (PICTURES)

Posted by Ram Kumar Shrestha on February 25, 2012

 

Recent earthquakes on Mars point at the existence of active volcanoes and liquid reservoirs that could sustain life on the Red Planet.

A recent quake with a magnitude of 7 is thought to have occurred after scientists analysed tracks made by boulders that toppled from a Martian cliff.

The paths of the rocks, which ranged from 6.5 to 65 feet in diameter, were captured by Nasa’s Mars Reconnaissance Orbiter, and were analysed by a University of London team. Read the rest of this entry »

GJ1214b, New ‘Water World’ Planet Confirmed By Hubble Telescope

Posted by Ram Kumar Shrestha on February 22, 2012

Astronomers have identified a new category of planet which is dominated by water.

GJ1214b, which was discovered in 2009, is a “water world” enshrouded by a thick, steamy atmosphere, researchers using Nasa’s Hubble Space Telescopehave confirmed.

The watery planet exists in a solar system known to already contain rocky, terrestrial worlds (like Mercury, Venus, Earth and Mars), gas giants (including Jupiter and Saturn) and ice giants like Uranus and Neptune.

Planets orbiting distant stars come in an even wider variety, including lava worlds and “hot Jupiters”.

Zachory Berta, of the Harvard-Smithsonian Centre for Astrophysics (CfA), said: “GJ1214b is like no planet we know of. A huge fraction of its mass is made up of water.”

GJ1214b was discovered in 2009 by the ground-based MEarth (pronounced “mirth”) Project, which is led by CfA’s David Charbonneau. This super-Earth is about 2.7 times Earth’s diameter and weighs almost 7 times as much. It orbits a red-dwarf star every 38 hours at a distance of 1.3 million miles, giving it an estimated temperature of 450° Fahrenheit. Read the rest of this entry »
